In a world where the demand for materials and energy continues to grow, industries face a central challenge: reducing their environmental footprint without compromising efficiency or quality. At Emsa Tecnología Química, we understand that sustainability is not a slogan — it’s a commitment embedded in every step of the value chain.
Jiangsu Liaoyuan, one of our partners and a global leader in sodium thiocyanate production, combines productivity with environmental responsibility. For years, it has employed a more eco-friendly process that recovers sodium thiocyanate from coke plant wastewater.
Thanks to this method, over 40% of CO₂ emissions are reduced compared to conventional cyanide-based synthesis. Additionally, by reusing ammonia and residual heat, energy savings are achieved while minimizing environmental risks.
What is sodium thiocyanate?
Sodium thiocyanate is a versatile inorganic salt used in multiple industries. Instead of being synthesized from virgin cyanide, the sodium thiocyanate we distribute at Emsa Tecnología Química is recovered from coke plant wastewater — transforming waste into a high-value resource.
Key features and benefits
- Improved yield strength: enhances internal cohesion, increasing mechanical resistance and extending product life.
- Grinding efficiency: optimizes the crushing process, reducing energy consumption.
- Greater durability: due to its stability under extreme temperature and humidity, it enhances long-term performance in final applications.
- Cost savings in cement production: acts as a setting accelerator, reducing construction times and associated storage costs.
Main applications
- Construction: as an additive in cement and concrete to accelerate setting and enhance early strength.
- Metallurgy: used in electroplating processes for copper, silver, and nickel coatings on copper and tin alloys, ensuring high-quality finishes.
- Textile and Polymers: serves as a solvent and intermediate in the production of specialty polymers and in the spinning and dyeing of acrylonitrile fibers.
- Agrochemicals: a precursor in the synthesis of pesticides and biocides, offering versatility in crop protection formulations.
At Emsa Tecnología Química, we believe every raw material choice should promote both efficiency and environmental protection. With sodium thiocyanate from Jiangsu Liaoyuan, industrial processes are optimized while advancing a circular economy model — where waste becomes a valuable resource.
Together, we move toward a more responsible and competitive industry.
